Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section
Wind Energy, Volume 29, Issue 2, February 2026.ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...
